did it drive fine before you put all that stuff on there. if so, why did you put that stuff on ?
check the center bracket as some people reported clunking and watch for oil leak from the bolts. read this thread https://www.ford-trucks.com/forums/1...oud-clunk.html

I have Kelderman with Fox and no vibration. I dont think if everything is tightened up right you will get vibration from adding a dual steering stabilizer.

I experienced the bottom out sound one time and never even dawned on me that’s what it could be I have since took the kelderman off to see if it helps the vibration is definitely less the steering feels a little easier but when I took it off the bar that the shocks were mounted too I can push it up not sure if there should be slip on it at all

The ends that Ford uses have some acceptable up and down play. There is a spring inside.


Found it, bellow is wording from one the Ford FSA's having to do with steering oscillation. If you are seeing more movement than stated here then you might have a problem.

NOTE: If inspecting the steering drag link and tie rods, by design there will be 1-2 mm of vertical movement when pushing on or rotating the drag link and tie rod ends. This movement is characteristic due to the internal spring design and parts should not be replaced for this normal condition. Refer to the WSM procedures in Section 211-03 for additional information.

Take that junk off. A dual stabilizer doesn't stop or fix death wobble. If you have death wobble, it's from worn parts or a crappy alignment. Simply replace the worn parts and do a proper alignment and it goes away...

A stock rig doesn't need a dual stabilizer. Even a rig with slightly bigger tires doesn't need one.

so you don’t think a dual steering stabilizer would help keep the front end tight and avoid dw

Good marketing and shiny stickers.

Steering stabilizers, single, dual or otherwise, are a band-aid fix for a larger problem. There is an inherent issue with the coil sprung Super Duty front end, stemming from loose tolerances and poor geometry. The positive effects of this are a soft riding, easy steering truck. The negative effects are obvious.

my thing is that Ford thought good enough to put one on that’s where the dual made sense to me but since taking it off I believe it drives better so now I’m back to is it worth to upgrade the stock one and if not how do you know when it goes bad and needs replaced
i don’t know much about this stuff so your guys help is great

No. When death wobble occurs, what happens when you hold the wheel tighter? It gets worse. Adding more stabilizers is the same as you just holding on tighter. Just fix the root problem of the worn part...

because everyone believes this misconception that more is better. Then they blame ford when there's vibration or other things going on like this guy has. Why not 3? Why not 10? Why not 20?

One is all you need. it's job is to smooth out the shock from road hits, not to stop death wobble

So when should you change out the factory stabilizer and are they all the same meaning will a bilstein be as good as a fox and so fourth

Change it whenever it leaks, or if you feel like you're getting too much road feedback. They're not all the same, so.e are stiffer than others. Fox has one that you can adjust the charge pressure to change the feel.
